Reducing power consumption and increasing battery life of nodes in an ad hoc network requires an integrated power control and routing strategy. The power control is achieved by new route selection mechanisms for MANET routing protocols, which we call energy-based time delay routing (EBTDR) and highest energy routing (HER). These algorithms try to increase the operational lifetime of an ad hoc network by implementing a couple of modifications to the basic DSR protocol and making it energy efficient in routing packets. The modification in EBTDR is enabled by introducing a delay in forwarding the packets by nodes, which is inversely proportional to the remaining energy level of the node, while in HER the route selection is based on the energy drain rate information in the route request packet to improve the fidelity in selection as it provides an optimized solution based on the link traffic in the network. It is observed from the simulation results that the proposed algorithms increase the lifetime of mobile ad hoc networks, at the expense of system complexity and realization.
